Dell OptiPlex compatibility

This 300 W ATX unit replaces the H300EGS-00, HU300EGS-00 and J82T5 modules used in OptiPlex 3667 3668 3669 3660 5050 3050 7050 and T3420 systems. It delivers the 6-pin connector those chassis require. Builders working on other small-form-factor platforms should verify pinout and depth before ordering.

Sustained-load behaviour

80 PLUS Gold certification means the supply maintains high efficiency across the load curve, keeping waste heat and fan speed low during long sessions. Resonant LLC topology with DC-to-DC conversion provides stable voltages under continuous demand and supports modern standby sleep states without rail droop.

Installation notes

The unit fits the standard OptiPlex mounting points and uses the proprietary 6-pin motherboard connector, so no adapter cables are needed. Zero RPM fan mode eliminates noise at idle, though the fan will spin up under heavier sustained loads. Ensure the chassis airflow path is clear; restricted vents are the most common cause of thermal throttling in these compact cases.

This unit fits OptiPlex 3667, 3668, 3669, 3660, 5050, 3050, 7050 and T3420 systems that require the 6-pin connector.

Will the Modern Standby feature work with an older OptiPlex 3050 I keep?

Modern Standby compatibility enables extremely fast wake-from-sleep and better low-load efficiency on supported platforms such as the 3050.
